Revision 1.7 2003-06-01 21:38:06 peter
|
|
* getregisterfpu size parameter added
|
|
* op_const_reg size parameter added
|
|
* sparc updates
|
|
|
|
Revision 1.6 2003/05/24 13:39:32 jonas
|
|
* fsqrt is an optional instruction in the ppc architecture and isn't
|
|
implemented by any current ppc afaik, so use the generic sqrt routine
|
|
instead (adapted so it works with compilerproc)
|
|
|
|
Revision 1.5 2003/04/23 12:35:35 florian
|
|
* fixed several issues with powerpc
|
|
+ applied a patch from Jonas for nested function calls (PowerPC only)
|
|
* ...
|
|
|
|
Revision 1.4 2002/11/25 17:43:28 peter
|
|
* splitted defbase in defutil,symutil,defcmp
|
|
* merged isconvertable and is_equal into compare_defs(_ext)
|
|
* made operator search faster by walking the list only once
|
|
|
|
Revision 1.3 2002/09/18 09:19:37 jonas
|
|
* fixed LOC_REFERENCE/LOC_CREFERENCE problems
|
|
|
|
Revision 1.2 2002/08/19 17:35:42 jonas
|
|
* fixes
|
|
|
|
Revision 1.1 2002/08/10 17:15:00 jonas
